这项一组前后测试设计是为了评估在三级新生儿重症监护病房(NICU)使用噪声传感器光警报器后的声音分布和突然峰值噪声频率(SPN)及其相关事件。当声级达到>；=65 A加权分贝(DBA)时，警报被激活。使用报警器前1周和使用后1个月连续监测环境声级。接受呼吸机支持的患者使用前、后保温箱内平均声级分别为58.0+/-0.6和56.4+/-0.7dBA(t=8.619；p<；0.001)，而辐射加热床内平均声级分别为58.0+/-2.4dBA和58.1+/-2.0dBA(t=0.715；P=0.476)。在孵化器和辐射加热床中，声级<；58dBA的观察时间百分比增加了28%和4%(p<；0.001)。使用该装置后，孵箱内SPN发作次数从630次/d减少到185次/d，辐射加热床上SPN发作次数从2069次/d减少到748次/d。噪声传感器灯光报警器有效地降低了NICU中SPN的声级和发作次数。这可能会减轻患有危重疾病的新生儿的噪音压力。
This one-group pre-post test design was to evaluate sound distribution and sudden peak noise frequencies (SPNs) and the associated events after using a noise-sensor light alarm in a tertiary neonatal intensive care unit (NICU). The alarm is activated as the sound level reaches >= 65 A-weighted decibel (dBA). The environmental sound level was monitored continuously for a period of 1 week before and 1 month after using the alarm. The mean sound level in the incubator of patients receiving ventilator support before and after using the device were 58.0 +/- 0.6 and 56.4 +/- 0.7 dBA (t = 8.619; p < 0.001), whereas those at the radiant heated bed were 58.0 +/- 2.4 and 58.1 +/- 2.0 dBA (t = 0.715; P = 0.476). The percentage of observation time of sound levels < 58 dBA increased by 28% in the incubator and 4% at the radiant heated bed (p < 0.001). Episodes of SPN decreased from 630 to 185 times/d in the incubator and from 2069 to 748 times/d at the radiant heated bed after using the device. The noise-sensor light alarm effectively reduces sound level and episodes of SPN in the NICU. This may alleviate stress of noise for newborns with critical Illness.
